The Shield of Ogmur is a very rare untiered drop that serves as an alternative to the tiered shields for the Knight. Instead of inflicting Stunned, it inflicts Armor Broken on any monsters it hits, setting their Defense stat to zero for 4 seconds. making it great for weakening bosses with high DEF such as the Avatar of the Forgotten King.

The most practical use for the Shield of Ogmur by far is in the Parasite Chambers. To deal any type of noticeable damage to various enemies, and any damage at all to the boss, you need to Armor Break the enemy or boss. The barrels in the Parasite Chambers are placed for this specific purpose, but unfortunately most people can’t aim the barrels properly (you need to kick them), or they troll and shoot them at players. The Armor Break this shield grants is much more useful vs the Stun a normal shield would grant, especially because most enemies in this dungeon are immune to Stun. Think of the Shield of Ogmur in this dungeon like a aimable, personal barrel.

However, this is a situational UT and should be used as a swapout, not a primary shield. For example, the armor break is rendered useless on monsters with very low defense, or monsters that are very dangerous like Oryx the Mad God 2. However, it is useful when there is a group of players focusing on one boss and that one of the players in the group is another knight that has a tiered shield, as the boss or monster being focused on will be stunned and you are safe to break his armor. It can also be used well against enemies that are either immune to Stun or don’t benefit much from getting stunned, such as the enemies in the Shatters that have very high defense. It should be used as a primary shield against bosses that are stun immune, or enemies which die before the stun can be of use, as it has the greatest stat bonuses of all shields.

The Shield of Ogmur used to be a rare drop from an Event Chest in the Ocean Trench from 9th September 2016 to the 12th as well as an Event Chest in the Ice Cave from August 24th 2018 to August 27th 2018 (Month of the Mad God 2018).
